doi'l-N Plrlk-NTERr oreen;

T all whom it may concern Be it known that we, Gnonen E. PARKER and\VILLIAM ELLINGER, citizens of the United States, residing atFair-haven, in the county of Vernon, State of Missouri,- have inventedcertain new and useful Improvements in Corn-Planters; and we do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to corn planters.

The object of the invention resides in the provision of a corn planterwhich will deposit the seed at desired intervals during the movement ofthe machine and which is op erated to effect such depositing of the seedwithout the use of a checkrow wire.

A further object of the invention resides in the provision of a cornplanter which is operated without the use of a checkrow wire and whichwill enable the operator to determine whether the seed is beingproperlydeposited as the machine moves back and forth across" the field.

lVit-h the above and other objects in view the invention consists in thedetails of construction and in the arrangement and combination of partsto be hereinafter more fully described and particularly pointed out inthe appended claim. p

In describing the invention in detail reference will be had to theaccompanying drawings wherein like characters of reference denotecorresponding parts in the several views, and in which-- Figure 1 is aplan view of acorn planter constructed in accordance with the invention,only those parts ofthe plantere'ssential to the understanding of theinvention being shown. Fig. 2 a side view of a fragment of what is shownin Fig. 1, same being on an enlarged scale. Fig. 3 an enlarged sectionon the line 3-3 of Fig. 1. Fi 4 an enlarged section on the line H ofFig. 1. Fig. 5 a section on the line 5-5 of Fig. 1 on an enlarged scalewith the parts of the hopper shaft clutch in tripped position. Fig. 6 aview similar to Fig. 5 showing the parts of the hopper shaft clutch inthrown in or normal position. Fig. 7 a detail perspective view of afragment of the clutch rcleasing shaft and showing one of the yieldingterminal bearings of said shaft and Fi 8 a section on the line 88 ofFig. 1.

Referring to the drawings, A indicates the specification ofIietters'fatnt.

frame of the planter in which is rotatably mounted an axle 10 havingfixed on each end thereof the usual traction wheels 11 and whereby theframe A is supported in elevation above the ground during the operationof the planter. The frame A includes a forward cross member 12 and anintermediate cross member 13 upon which are supported spaced brackets 14and 15 extending longitudinally of the frame. Mounted upon the frame Aare seed hoppers 1G and 17 from which depend the usual shoes 18.Rotatably mounted upon the frame A and disposed transversely thereof isa shaft 19 which extends through the discharge mouths of the hoppers 16and 17 and isadaptcd by its rotationto intermittently effect thedischarge of the seed from the hoppers in the usual and wellknownmanner. 19 also extends through the brackets 14' and 1:).ltotatably mounted upon the frame A in yielding bearings 20 andextending through the brackets 11 and 15 forward of the shaft 19 is ashaft 21which has fixed on each end thereof ground wheels 22. Loose onthe shaft 19 between the brackets 11 and 15 is a wheel which has a hubextension on one side in the form of a ratchet wheel 21 and a hubextension on the other side in the form of a sprocket wheel 25. Fixed onthe shaft 15.) adjacent the ratchet wheel 24: is a wheel 26 which haspivoted thereon a Y- shaped pawl 27 disposed in embracing relation tothe ratchet wheel 26 and having one arm thereof provided at its free endwith a tooth 52$ adapted for coiiperation with the teeth of the ratchetwheel 24. The pawl 27 is normally held in operative relation to theratchet wheel 21 by means of a spring 29. Fixed on the axle 10 is asprocket wheel 30 disposed in alineinent with the sprocket wheel andtraveling on the sprocket wheels and 25 is a sprocket chain 31. By thisconstruction it will be apparent that as long as the pawl 27 ismaintained in operative relation to the ratchet wheel 24; the rotationof the axle 10 will effect a corresponding rotation of the shaft 19 anda resultant intermittent discharge of seed from the hoppers 16 and 17.Formed in the brackets 14 and 15 are alined inclined slots 32 in whichis movably mounted the terminals of a tripping rod 33, said tripping rodbeing normally held in the lowermost end of said slot by means ofsprings 34. In its normal position the rod 33 is disposed so as to beThis shaft engaged by the stem of the pawl 27,.di1-ring rotation of theshaftig19 and such engagement between the pawl 27 and rod 33 will"disengage the tooth 28 from the ratchet wheel and thus stop the rotationof the shaft 19 under 7 the influence of the rotation ofthe axle 10.

The movement of the pawl .27 as the result of engagement with the rod 83is limited by a stop 35 secured to the wheel 26.

Mounted upon the shaft 21 between the brackets 14 and 15 for rotationwith said shaft are triangular plates 36 disposed respectively adjacentthe inner faces of the brackets lt and 15, and which are adapted duringtheir rotation to lift the rod 33'upwarclly and thereby disengage samefrom the pawl 27. Each of the ground wheels 22 is provided withtriangular portions which bear the same relation to the shaft 21 as thetriangular plates 36. The peripheries of the ground 7 wheels 22areprovided with cleats 38' and marking fingers 39, the latter beingdisposed at the points of the triangular portions 37 and are adapted tomark the line in which a deposit of seed has occurred. The shaft 21 isprovided outwardly. of both the brackets 14 and 15 with knuckles 40which will permit theground wheels'22 to adjust themselves to unevenground without effecting the relation between the triangular plates 36and the trip rod 38.

In the operation of the planter the. rotation of the axle 10 will effecta rotation of the shaft 19 and result in a deposit of seed. As soon asthe shaft 19 has made one complete revolution the pawl 27 will be thrownout by engagement with the rod 83'and the rotation of the shaft 19stopped. The. ma-' chine will then move along the ground withoutefiecting any deposit of seed until the shaft 21 has been rotated so asto effect the elevation of the rod 33 and the disengagement of thelatter from the pawl 27. When. this takes place the rotation of theshaft 19 will be again instituted and another deposit of seed effected.This operation is repeated as the machine moves along the ground, thevarious parts being timed and adjusted so that the deposit of seed willtake place at desired distances apart. V

As the machine is returned across the field one of the ground wheels 22will travel in r the track previously made by same and the operator byobserving whether the fingers 39 are striking their previous marks candetermine if the proper deposit of seed is being effected. V

l/Vhat we claim is V In a planter, the combination ofa a wheeled axlesupporting the'frame and rotatably mounted on the latter, seed deliv;

ering mechanism mounted on the frame, a rotatable shaft-mounted on theframe and adapted by its rotation to operate thefseed deliveringmechanism, a sprocketijwheel frame,

16 loosely mounted on said shaft, a-conne'ction between said sprocketwheel'and axle for rotating the former, a ratchetwheel fixed to saidsprocket wheel, a disk fixed on the shaft, a pawl pivoted on the disk.for operative engagement with said ratchet wheel, means normally holdingthe pawl inoperative engagement with'the'ratchet' wheel, bracketsmounted on said frame, a tripping rod slidable in said brackets andnormally disposed in the path of travel of said pawlwhereby i theengagement of the latter with theformer will disengage the pawl from theratchet wheel, a second shaft rotatably mounted on the frame, tractionWheels fixed on the ends of said shaft respectively, and means securedto said second namedshaft adapted during the rotation of the latter tointermittently move the tripping rod out ofthe path of travelof thepawl. v l In testimony whereof, we aflix our signatures, in the presenceof two witnesses.
